[Frameworks] Developing Tanks for 16mm

[lindsay mcintyre]

Hi Rob,

In the G3 tank I've used several developers - these numbers are per 100ft
of 16mm - if I loaded 150-200 ft on the reel I would increase the times.
2L of each solution at room temp - might need more for 35mm.  Its important
to make sure that you are winding emulsion OUT at least half the time.
I've done it many times with other timings as well, based on the
temperature of the solution or whether the film was underexposed.  It
always seems to work pretty well.

D76 for 7222
dev 12 min (usually takes 1 minute to wind from head to tail so 12 winds)
wash 6 min
rapid fix 6-7 min
wash 7 mins

D19 for 7363, 7231 and most other B+W stocks
dev 5-7 mins
wash 5 mins
rapid fix 5-6 mins
wash 7 mins

Best,

Lindsay McIntyre
